The spectral model turbulence analysis technique is widely used to derive kinetic energy dissipation rates of turbulent structures (ɛ) from different in situ measurements in the A kinetic-fluid model describing the evolutions of disperse two-phase flows is considered. The model consists of the Vlasov–Fokker–Planck equation for the particles (disperse phase)

Triggered by the fact that, in the hydrodynamic limit, several different kinetic equations of physical interest all lead to the same Navier-Stokes-Fourier system, we develop in 1 Introduction The Fokker-Planck-Landau (FPL) equation is a kinetic model widely used in plasma physics. It describes the time evolution of charged particles in a plasma [21, 22]. When the
